We have performed diffraction experiments on polymer-stabilized cholesteric texture (PSCT) films made from E48-BAB6 mixtures cured at various UV intensities. The diffraction observed in these samples is the Qu'etelet-type ring pattern, which is generated from the scattering of light by the clusters of the polymer networks and the focal conic domains of cholesteric liquid crystals in a PSCT cell. We monitored the dynamic change of the intensity of the first ring of a sample during polymerization. After polymerization, both the electro-optical characteristics and the diffracted ring intensities of various orders were measured. The results showed that both the applied voltage and the UV curing intensity affected the diffraction intensity significantly. Furthermore, the results obtained from diffraction measurements correlate with the electro-optical ones. Thus, the diffraction measurements could provide us with another qualitative, nondestructive method to analyze PSCT devices.
